Potterphiles are likely already aware of this, but the more casual Harry Potter fan and his or her children may not be aware that in the end credits of the third Harry Potter movie, Prisoner of Azkaban, there is an Easter egg that implies sexual lasciviousness.

Check out the footprints in the bottom, lower left hand corner. Look closely.

As illustrated in the Marauder’s Map (which tells you where everyone in the school is located), that looks like it’s suggesting a good old-fashioned snogging in a hidden corner of Hogwarts. Who do those feet belong to, and what are they getting up to?

Not too long ago, HuffPo caught up with the man who designed the credit sequences, Rus Wetherell, and asked the man for the scandalous details. Was that Harry and Cho Chang getting frisky? Was Neville showing off his longbottom?

Alas, it was all very innocent, assured Wetherell, and not meant to be specific to any one character.

“Maybe it was meant to be Harry, but we’ve all been kids, we’ve all been in school and stuff … It was just a sort of little peck on the cheek,” he said.

Boo!

But those boots were knocking right up against each other. Those crazy kids must have been smashed right up against each other, and the movement of those shoes suggests something out of a Grey’s Anatomy supply closet, right?

In Wetherell’s mind, the couple’s feet “are in an embrace” and “not having sex as everyone says.” The addition of the feet ended up making the final movie because, when director Alfonso Cuarón spotted the moment, he started laughing and “just went nuts.” As Wetherell explained, Cuarón liked that “it was just something there that was amusing for the adults in the audience and kids wouldn’t really understand.”

Originally, Wetherell suggested doing more with the feet, but Cuarón told him no, just leave them and move on. “It was just a little light heartedness and bringing a bit of a smile to people,” said Wetherell.
